IDENTIFICATION AND AMS RADIOCARBON DATING OF CHARCOAL FROM THE GAME DRIVE SITE, 5LA5484, ON THE PIÑON CANYON MANEUVER SITE, COLORADO

Two charcoal samples from an excavation unit at the Game Drive Site (5LA5484) on the Piñon Canyon Maneuver Site in Las Animas County, Colorado, were submitted for identification. A single radiocarbon date also was obtained from charcoal in one of the samples. This site is a large complex of rockshelters, rock art, bedrock metates, thermal features, and lithics. Diagnostic projectile points and rock art suggest occupation within the Developmental to Diversification periods (A.D. 100-1050 to A.D. 1050-1450). Charcoal identification will provide information concerning woods burned as fuel at the site, and an AMS radiocarbon date will help confirm occupational sequence of the site, as well as aid in assessing eligibility of the site for inclusion in the National Register of Historic Places.来自科罗拉多州拉斯阿尼马斯县皮尼恩峡谷演习场（Piñon Canyon Maneuver Site）内狩猎驱动遗址（Game Drive Site，编号5LA5484）的一处发掘单元的两份木炭样本已送检鉴定。此外，从其中一份样本的木炭中获取了1组放射性碳测年（radiocarbon date）数据。该遗址是一处大型复合遗存点，涵盖岩棚、岩画、基岩磨盘、热活动遗迹与石制品遗存。具有诊断意义的投射尖状器与岩画遗存表明，该遗址的人居活动年代处于发展期至多元化时期（公元100年—1050年至公元1050年—1450年）。木炭鉴定将可获取该遗址作为燃料使用的木材种类相关信息，而加速器质谱（AMS）放射性碳测年则有助于确认该遗址的人居活动时序，同时可辅助评估该遗址是否符合列入《国家历史遗迹名录》（National Register of Historic Places）的资格。
